BANGKOK - The US ambassador in Thailand said on Thursday night that the acting Thai prime minister is not at the US embassy in Bangkok.

Ambassador Kristie Kenney was commenting on reports that Mr Niwuttamrong Boonsongpaisan was seeking refuge at the US embassy after Thai army chief General Prayuth Chan-ocha announced that the military had taken over control from the government.

"Absolutely false. Do not believe rumors," the US diplomat tweeted.

In another tweet, the US embassy warned of "fraudulent postings and rumors circulating online''.

The Nation news website had earlier reported that Mr Niwuttumrong did not attend the meeting hosted by the army chief at the Royal Army Club intended to find a solution to the ongoing political crisis. All rival groups were invited to the second day of talks on Thursday.

The premier had been absent from the meeting since the first day, claiming he was the premier and will not attend the meeting hosted by the army chief.

Thursday's meeting was inconclusive as well, reported The Nation.

At 5.00pm local time, General Prayuth announced on TV that the military had taken over control of the government. The constitution was suspended and members of the deposed government were told to report to the military by end of Thursday.

All protesters were told to go home and a curfew was set throughout Thailand from 10pm to 5am.
